Maybe a mode whereby we are fighting the bosses in the traditional IB formula?Like Fire->Ice/Water->Earth-> Etc. instead of the current megaman-esk style.

Actually I'd rather have this be the default mode, and maybe only opening up the boss selection after clearing them for the first time. Of course the current formula always opens up more variety for the new players as they can try their hands on the different bosses instead of repeatedly getting killed by one. And can also create strategies, approaches and whatnot.

But I was always very thrilled because with the old formula - having to rely on pubscrubs means I am always blown away after clearing a boss for the first time and then getting my ass delivered to me in a handbasket by the new abilities and overall theme of the next boss. (It was hilarious seeing my friends getting Raekt by Raezon the first time.)

Just a little something to bring back the nostalgia of the old IB days perhaps ?

I think the boss' difficulties need to be closer for the selection to actually add depth (i.e., when we used to delay light/shadow/ice to wait for ob + inf was interesting). Right now it feels more like an "illusion of choice". Whether that needs changing though, I'm undecided on it.
